Watch The Whole Story with Anderson Cooper

CNN Senior National Correspondent David Culver returns with an immersive dispatch from inside the brutal cocaine trafficking system which has made Ecuador the deadliest country in Latin America. Since 2018, Ecuador's homicide rate has surged by 580%, with 2025 on track to be Ecuador's deadliest year on record. With roughly 70% of the world's cocaine moving through Ecuador, gangs are at war for control of an underground global economy worth tens of billions of dollars a year. In "Ecuador: The Narco Superhighway," Culver goes deep inside a system that pulls in the poor, empowers the brutal and protects the powerful, all to indulge the habit of a global addiction with local Ecuadorians caught in the undertow. "We spent more than two weeks in fishing villages, border towns, major cities and ports… places where the violence isn't just a headline, it's part of daily life. We met grieving families, fishermen pulled into the trade, even gang members who claim they had no other option but to commit horrific acts, which they openly admit to," said Culver. "This isn't just a story about drugs. It's about how power, poverty, and global demand collide in Ecuador." From coastal villages and jungle borderlands to banana plantations and bustling ports, and even to the Galapagos islands, Culver follows the chain of smuggling, extortion and violence. He rides along with Ecuador's navy as they train to chase down drug runners off the vast Pacific coast and speaks with a high-ranking gang commander reflecting on the impact of his trade on his community.

CNN Chief Climate Correspondent Bill Weir returns with a look at some of the biggest stars working to revolutionize the eco footprint of live music. Featuring Billie Eilish and her mother Maggie Baird, Bonnie Raitt, Jack Johnson, AJR's Adam Met and Perry Farrell formerly of Jane's Addiction, Weir traces the legacy of stars who are working to reform a live music industry that demands massive amounts of energy and produces tons of waste. From refillable water stations, plastic-free shows and even kinetic dance floors that turn the crowd's energy into electricity, eco-conscious musicians are leading a movement to make caring about the climate cool. Their influence is catching on, with Lollapalooza now operating its main stage with a battery-powered hybrid system that gets cleaner every year, and Coachella implementing their first zero carbon stage. "As so many politicians and corporate leaders slink away from leadership on climate issues while the cultural influence of live music explodes, I set out to understand how a handful of devoted artists have managed to clean and green their industry in astounding ways," Weir said. "A music festival is like a temporary, disposable city so the lessons learned can be applied across society, and the connections being made with fellow fans have sparked a surprising new wave of grass roots connection and action." Weir speaks with Billie Eilish behind-the-scenes during her stadium tour where she implements several eco-friendly initiatives, and meets up with her and Maggie Baird in the hills of Los Angeles where nonprofit Tree People plants shade in underserved communities and after wildfires. He also visits with Jack Johnson on his Kokua Learning Farm in Hawaii, created to connect kids with nature and fresh, healthy food.

CNN Anchor/Senior National Correspondent Sara Sidner returns with a powerful portrait of a multi-racial Southern family that confronts and explores its painful shared history— and comes together in spite of it. In York County, South Carolina, two halves of the Simril(l) family exist: the white side, descended from slave holders, and the Black side, descended from people enslaved on the Simril plantation. The two were segregated for over a century— unaware of their shared background— until Spenser Simrill began reaching out to others with the same last name 11 years ago, in the hopes of learning more about his family's clouded history. What he and his newfound relatives uncovered was a complicated legacy built around slavery, Reconstruction Era racial terrorism, and the unbelievable villains and heroes at the center of it. As they prepare for their 2025 reunion celebration, Spenser Simrill and Michael Simril continue their search to unearth more of the Simril(l) story. They investigate their ancestors' violent run-ins with Klansmen in the county, as well as their family's 1871 migration to Liberia in pursuit of economic prosperity. Together, the Simril(l)s of today consider how their blended families can share resources moving forward, enrich each other's lives, and serve as a blueprint for racial healing. "The Simril(l) lineage is full of remarkable characters who were unafraid to challenge power at fraught times in our nation's history," said Sidner. "I was so taken not only with their story, but also their ability to embrace it with such grace and dignity. As we look to the Juneteenth holiday, I see this family as a model for how we can all reckon with our pasts to forge a better, more united future."

CNN Anchor and National Correspondent Erica Hill takes a deep dive into the future of Venice, a city threatened by rising sea levels and the millions of tourists desperate to visit while they still can. Much of the world fears that climate change and rising sea levels will soon sink the ancient city of Venice, a misconception that is causing millions of tourists to visit each year while they still can. In "Saving Venice," Hill discovers that the more imminent threat to Venetians' way of life is this overwhelming flood of tourists, transforming the city's culture, housing and local economy. Hill speaks with a collective of locals interested in promoting a more ethical tourism industry with respect for Venice's unique and delicate environment. She learns about the innovative ways a new generation of Venetians are working to preserve the city's traditions, mitigate the effects of climate change, and taper the city's dependance on massive amounts of tourists. "The rich history of Venice is one of innovation, evolution and entrepreneurship," said Hill. "That legacy is being tested now more than ever, but there are sustainable, thoughtful solutions to save this beautiful city, its culture, and most importantly, its community. With unique access to the Venice many visitors don't see, I am hopeful this hour will introduce audiences to a city - and a story - that is also a critical wake-up call for others around the world." The episode features interviews with local Venetian restauranteurs, artisans, oceanographers, city planners and more. Hill even gets a rowing lesson in the canals of Venice from a competitive rower whose family has been competing in the city for generations.

As the crisis enters its "third wave," Bolduan engages with emergency medical technicians, physicians at treatment centers and people struggling with addiction themselves, all seeking new solutions to a decades-old problem. "These past two years have been a uniquely powerful and educational experience for our team. I am grateful to all our interviewees who bravely allowed us in and shared their stories," said Bolduan. "We witnessed first-hand the extraordinary challenges that come with breaking free from the cycles of addiction, and I am hopeful this project will illuminate the human element of the crisis and encourage others who are struggling to seek treatment." "Fentanyl in America" features remarkably candid and intimate interviews with people struggling with addiction. Pregnant women, families, and even drug dealers reveal to Bolduan the harsh realities of illicit fentanyl, a crisis that has propelled new treatment programs. She rides along with the first emergency medical service in the nation to carry buprenorphine, a treatment for fentanyl withdrawal that a study has associated with a nearly sixfold increase in the odds of engagement with addiction treatment. Bolduan also visits a center providing methadone treatments, where some people must visit every day for their daily dose.

Chief Climate Correspondent Bill Weir returns with an exploration into how human life as we know it is adapting to our changing climate. He seeks answers to how humankind can survive and thrive in an age of heat, drought, flood, and fire. His quest to find the heroes and innovators on the frontlines of this issue takes him across the globe, where he finds heroes building happier, healthier, and stronger communities built to withstand extreme weather in any form it takes. "When I became a new dad in 2020," Weir said, "I looked down at my son and thought ‘Where will he be safe? 'What kind of shelter will he need? Who is building the smartest, safest, and most resilient communities?' His arrival helped spark this worldwide hunt for inspiration and in the end, I returned with a lot more hope than fear." From a new "policy of shade" in scorching Phoenix to a floating neighborhood outside of Amsterdam to the rise of disaster-proof construction, Weir finds those on the cutting edge of adapting our way of life. With visits to London and Silicon Valley, he reveals the inventions and startups that have the investment blessing of Bill Gates and Tom Steyer.

CNN Senior Investigative Correspondent Kyung Lah presents an in-depth look at the unusual star-making K-Pop industry in South Korea. K-Pop idol bands have fan bases all over the globe, hugely popular musicians and songs originating from South Korea. But these bands are molded and created in a way unlike anything else in the music industry. Aspiring young stars take on rigorous vocal, dance and fitness training from early morning to late at night, some even leaving school and living in dorms away from their families. In "K-Pop: A Star is Made" Lah embeds in the strenuous training process of seven aspiring K-Pop stars in a small studio in the heart of Seoul, South Korea when they are just one week away from auditioning for the studio's premiere idol group. "As a Korean American growing up in Chicago, I never imagined my native language would be streamed across platforms in the US as a multi-billion-dollar industry," said Lah. "It still shocks me to this day. What I wanted CNN's audience is to see and experience how this happened, through the intimacy of the struggle of the K-pop trainees you'll meet in our hour. They're more than perfect young men and women of the TikTok era — they're utterly human, some as young as 14, and as vulnerable as the young fans who listen to them." The episode features interviews with Amber Liu, Megan Moon and Min who talk about the global impact of this explosive industry, which also comes with international scrutiny for its stars. Lah also speaks with the trainees about the pressure to maintain a certain appearance, and how extreme dieting and plastic surgery are common amongst K-Pop hopefuls.
